Mechanism compares, and has saved space, shortens to be formed, and structure becomes compacter.
The utility model is realized in this way a kind of screw thread core pulling mechanism for multi-cavity mold is constructed, including round tooth
Wheel, driving gear and the driven gear for being fixedly installed in core, the interior outside of the circular gear are both provided with tooth, the driven tooth
Wheel be located at round tooth on the inside of, and with the interior tooth engagement of circular gear；The driving gear is connect with external connection power source, and with circle
The outer tooth engagement of gear.
Preferably, the driven gear is multiple, is not interfere with each other, and with being engaged on the inside of circular gear.
Preferably, it is provided at the top of core matched with driven gear and the matched external screw thread A. of product, bottom setting
Have and the matched external screw thread B. of mounting blocks.
Preferably, the core top is matched by sleeve with cope plate, and the cavity and cope plate of top and lower template
Cavity formed product product cavity.
Preferably, the mounting blocks are installed on the Bottom clamp plate of mold.
Preferably, circular gear, driving gear, driven gear are synchronous with the movement of core axis direction.
The utility model has the following advantages that：
Advantage one：The utility model is designed reasonably, it is simple in structure, it is easy to use, for the screw thread core pulling of mold, pass through conjunction
Reason design circular gear, instead of traditional rack, so as to reduce space during core pulling, shortens stroke, also can
Fast and convenient completion inner threaded core-pulling, while compared with traditional inner threaded core-pulling mechanism, saved space, shortened row
Journey, structure become compacter.
Advantage two：The utility model has not only saved space and has shortened stroke by reasonably designing circular gear, leads to
Outside is respectively provided with tooth including crossing, and arrangement can uniformly be installed on the inside of circular gear by realizing core, finally realize multiple systems
The core pulling of part can be adapted for the inner threaded core-pulling of multi-cavity mold.
Advantage three：Newly installation and removal are simple for this practicality, and convenient for maintenance from now on, and structure is compacter, with tradition
Screw thread core pulling mechanism is compared, space structure smaller.
Advantage four：The utility model manufacture is easy, and of low cost, use scope is wide, can improve production efficiency, is suitble to big
Range is promoted the use of.
